QUIMBY S. BAOKUS, OF BRANDON, VERMONT.

WATER-H EATER.

SPECIFICATION forming part of Letters Patent No. 787,656, dated April18, 1905.

Application filed December 13, 1904:. Serial No. 236,708.

To all whom it may concern:

Be it known that I, QUIMBY S. BACKUS, a citizen of the United States,residing at Brandon, in the county of Rutland and State of Vermont, haveinvented certain new and useful Improvements in VVater-Heaters; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichitappertains to make and use the same.

My present invention relates to the class of gas-heaters for heatingwater brought to the heater from any source of supply through asupply-pipe; and it consists in certain improved constructions andcombination of parts whereby a cheap and eflicient heater is produced.

In the drawings 1 have shown a waterheater embodying my invention, andsaid invention is disclosed in the following description and claims.

In the drawings, Figure 1 is a view of my improved heater in elevation,and Fig. 2 is a vertical section of the same.

In said drawings, A is the inclosing casing for said heater, which isprovided with a lining of asbestos a to prevent radiation of heat. Theheating of the water is eifected in a coil of pipe B within said casing.This coil is a continuous coil having its two ends adjacent to thebottom of the structure, to one end of which is attached the supply-pipeb, and the other end is connected to the discharge-faucet b on theoutside of the casing. The end coils of this heater are brought in closeproximity to each other and the coils above come together and intersectand overlap each other, as shown in the drawings. The burner C is placedin the bottom of the casing and extends laterally, so as to bring theouter sides beneath the ends of the coil.

preferably constructed of a pyramidal or like form and is provided atits upper part with centrally-disposed flame-openings 0, giving verticalflames, and below this it is provided at its sides with one or morerowsof flame- This burner is openings 0', directing their flames within thecoils and against the portion of the pipes of the coils nearest theburner. The flamesfrom the upper orifices will be directed toward oragainst the interlapped and other coils above the burner. This burner ispreferably an injector-burner or one designed to burn such an admixtureof air and gas as to insure complete combustion.

O is the gas-supply pipe, and c the cock controlling the same.

This construction gives a large heating-surface and so distributes thesame as to utilize the greatest amount of heat produced by the burner.

By making the heating-coil in the form shown I am enabled, by changingthe length of the coil and the size of the burner, to construct heatersof varying capacity from the same materials.

What I claim, and desire to secure by Letters Patent, is

1. In a water-heater, the combination with the casing of a burner andheating-coil within said casing, said heating-coil being composed of acontinuous pipe and including nearly vertically-disposed spiral coils atthe incoming positions directly above the burner, sub-' stantially asdescribed.

In testimony whereof I affix my signature in the presence of twowitnesses.
